The head of the Russian Olympic delegation, Igor Kazikov, confirmed on Thursday that it would be taking 650 members to Rio, including 380 athletes.

Originally Russia planned to send 430 athletes to the event, but with the Russian track and field team still suspended from competing by the International Association of Athletics Federations (IAAF) the number is now reduced, Kazikov explained.

In June, the International Olympic Committee (IOC) upheld the IAAF's decision to leave Russia's ban in place, with numerous issues yet to be resolved over the country's implementation of an adequate policy to tackle doping and corruption issues.

"Although good progress has been made, the IAAF council was unanimous that RUSAF [The Russian Athletic Federation] had not met the reinstatement conditions," stated IAAF head Sebastian Coe.

Russian sport has been beset by problems since the publication of a World Anti-Doping Agency (WADA) report in November 2015 that pointed to a large number doping violations.

However, the IAAF ruled in June that 'clean' Russian athletes will be able to apply for permission to compete in the 2016 Summer Olympics if they can prove they have not taken banned substances.
